Krell KAV-300i or any other high powered integrateds would be my pick. The Mark Levinson looks good too. I briefly owned the N805 many years ago and the Krell matched well the B&W. I also tried YBA Integre DT with it and got good results, higher refinement than the Krell but it lacked the grunt and bass power especially at higher volume listening. The speakers require good power or current to open up and sound good. Avoid low or modest powered amps if possible.
Good luck.
